Is the fan in a convection oven noisy?

The fan in a convection oven is generally not very noisy. Most modern convection ovens are designed to operate quietly, with fans that produce minimal sound while circulating hot air for even cooking. However, the noise level can vary depending on the specific model and its age, with older ovens potentially being louder due to wear and tear. Overall, the fan noise is usually a low hum that shouldn't be disruptive.
